Pairing studies using a cross table or scatter plot.

[Juan Vaca]

Ok, I got a request to show a table with the number of sites participating in each possible pair.

If two studies are being done in a location then it would count as one.

I would be using two columns "study" and "location".

eg. If there are 32 locations where Study 1 and Study 2 exist then 32 would go in the box (see below).

some ideas would be helpful. Please reachout to me if you need further explanation.

 

Here is an example

 

 

 

Study 1

Study 2

Study 3

Study 4

 

 

Study 1

Study 2

32

Study 3
